Blown Posi FOR THE LOSS! This was my first run of the night, but I found a way to keep both spinning during the burnout. Problem was, even on my good launches, about 30 ft out, the posi lets go and it kicks power from one rear wheel to the other allowing it to spin some, or crab walk is what it feels like up to about 40-45 mph.

Check the rollout on the tires. Not uncommon for them to be different. If they're over an inch different, it can unload the posi. The radials are a lot better then bias tires in that aspect, they're all pretty much the same size

I noticed in this vid that you did a quick spin in the burnout box and pulled forward. That's actually how I did burnouts for years. That was a good reminder for me, I think I'll do that with the Camaro.
